Perhaps you should try some spelling variations:
"d'economies politique" » "d'economie politique", "l'economie politique", "d'economie politque", "d'economics politique", "d'economiques politique", "d'economys politique"
"economics politique" » "economico politique", "economico politiques", "economics political"
"economie politique" » "economic politique", "economique politique", "economy politique"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("economie politique") OR ("economics politique"))) OR ("d'economies politique")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"economie politique\") OR (\"economics politique\"))) or (\"d'economies politique\"))".
• Removing quotes may allow a broader search: (((( economie politique ) OR ( economics politique ))) or ( d'economies politique )).
• Adding a wildcard symbol may retrieve word variants: (((("economie politique") OR ("economics politique"))) or ("d'economies politique"))*.
